What is inside that parentheses is then scalar product (inner product) of those two vectors, the result of which is 4 which then multiplies the rightmost matrix and then this is substracted from the first one.

In general, if you have two linearly independent vectors , then is an orthogonal vector to , as can easily be checked (here, denotes the inner product of the vectors)
